Multi-mode optical pointer for interactive display system

摘要: Control of a presentation computer is accomplished by wireless optical pointer that projects an encoded control cursor onto projection screen in interactive system. The selectively operable position-dependent, spot mode actuation first push button switch enables remote initiation various keyboard commands and/or pointing device (mouse, touch pad, track ball) position-dependent operations, e.g., select, move, left click, right click and double click.
